andyvuong commented on issue #1131: SOLR-14134: Add lazy and time-based evictiction of shared core concurrency metada… URL: https://github.com/apache/lucene-solr/pull/1131#issuecomment-571242869 > And for regular eviction we do not need this tracking either, we can simply do that in SolrCore#close. The basic assumption is: if core container can hold so many SolrCore instances we can very easily hold this simple metadata. The problem of many cores is planned to be addressed by transient cores or zero replica design. With that I don't think this cache need to worry about its own size as long as it ties itself with SolrCore instances. @mbwaheed we can evict lazily on on SolrCore instance creation in addition to SolrCore#close. To clarify you're also saying we can scope this item smaller and stick with a simpler cache (simple map, no size/time based eviction as done here) and let that future item handle whatever is needed ?
